Jabil reported FY2025 results with revenue of $29.8B, up 3.2% year-over-year, and diluted EPS of $5.92, with gross margins at 8.9% and net margins at a slim 2.2%. The earnings beat was driven by accelerating demand from AI infrastructure customers — data center and hyperscaler clients pulling forward orders for server components, power systems, and cooling assemblies. The stock jumped on the print, but the headline from Yahoo Finance flags that JBL is 'no longer cheap,' implying the post-earnings gap has compressed the margin of safety.

Jabil sits in the electronic manufacturing services (EMS) space alongside Foxconn and Flex, where thin margins are structural — 2.2% net is not an aberration, it is the business model. The AI tailwind is real: hyperscalers are spending aggressively on infrastructure, and Jabil's diversified manufacturing footprint makes it a credible beneficiary. But a re-rated EMS name trading at a premium multiple is a different risk proposition than an under-the-radar compounder.

The bull case rests on the durability of AI capex and whether Jabil can sustain above-trend revenue growth that justifies a higher-than-historical multiple. The bear case is straightforward: if AI capex plateaus or customers bring more manufacturing in-house, a thin-margin business with limited pricing power de-rates quickly. The 3.2% revenue growth rate, while positive, is not explosive enough on its own to anchor a stretched valuation.

The key watch items are forward guidance on AI-related segment revenue, any commentary on customer concentration among hyperscalers, and whether the gross margin line can expand meaningfully beyond 8.9% as mix shifts toward higher-value AI work. A guidance cut or margin miss in the next quarter would likely unwind a meaningful portion of the post-earnings re-rating.
